“…where Q is the energy deposited, C s the specific heat capacity of the aluminium conductor, ΔT m = T m -T 0 , where T m is the melting temperature and T 0 the initial temperature, h m the melting heat, C f the heat capacity of the liquid metal, ΔT = T -T m , where T is the final temperature, and T m the melting temperature (Tkachenko et al 2004). It is clear from the magnetic pressure plot (figure 4) that the magnetic pressure exerted on the surface layer is zero.…”
